I don't have anything simple enough to paste here, so I'll make up a
contrived example for user registration:
public Resolution execute() {
User user = registrationService.registerUser(username, password,
email);
// let's create an empty user profile for the newly created user
to store their settings
UserProfile profile = userProfileService.createProfile(user);
}
Now if the createProfile() method throws a RuntimeException for
whatever reason, the user will see an error page. The user will
reasonably think that registration failed, when it in fact succeeded.
I would prefer that the registration gets rolled back.
